As past over long service time, parts abrasion universally or cylinder severely damaged, a new measurement transducer should be installed to replace old one. As find exterior leakage, firstly inspect the bolts corresponding to leak section. Tightly screw loose bolts, if leakage is continued, disconnect and inspect the seal ring and gasket relative section. Substitute aging or damaged parts and reassemble. Apart from the above reasons of extensive colloid and surface abrasion, these trouble also cause abnormal operation of measurement transducer, such as position pin fall down from piston or deformation, small axis lost on upper and lower connecting rod, loose bolt between piston and connecting rod. The solution is that disassembling measurement transducer, replace damaged or unqualified components and reassemble. The products made in normal factory seldom appear these trouble fuel dispenser s. Since measurement transducer is core component of fuel dispenser, elaborate machining, disconnection and reassembly should be as care fuel dispenser ful as possible. All elements should be cleaned before reassembly, excluding water into inner. Bolts are tightened even and appropriately. Soft-piston measurement transducer As these merits --- small in size, light weight, beautiful appearance, high accuracy, piston exchangeable--- soft-piston measurement transducer is widely adapted in domestic fuel dispenser market. It generally involves two structures: four-piston structure and double-piston structure. The latter model is selected universally. Therefore, this article will introduce the structure, working principal and maintenance of four- piston measurement transducer. Structure Diagram 2-20 and Diagram 2-21 show the cutaway view and exploded drawing of four-piston measurement transducer that is widely employed. The transducer mainly consists of sealed cover, upper subassembly, export axis, frame subassembly, piston subassembly, connecting rod and top cover, clearly presenting in Diagram 2-20 and Diagram 2-21.

ration, explosion of the banlieues—Le Pen told you so!�? In any case, fears over immigration, crime and security are now a mainstream concern, not just an extremist one. In the words of Robert Badinter, a senator, there has been a “LePen-isation�?of French minds. These days, when Mr Le Pen talks about a “migratory invasion�?and gives dark warnings that “the original population is going to be submerged�? not everybody is shocked; the language of the political centre has also moved that way. Apart from fiery rhetoric, Mr Le Pen has some concrete demands an immediate expulsion of all illegal immigrants, and a tightening of the nationality law. He deplores the recent decision by Mr Sarkozy, as interior minister, to grant amnesty to a third of the illegal newcomers whose children attend French schools. Yet immigrant-bashing populism is only one source of Mr Le Pen s fuel dispenser high ratings. Nearly as appealing are his attacks on the “elite”—the close-knit political class. The feeling that real power in France l fuel dispenser ies with a network of cronies has always been strong (on the communist left as well as the right) and Mr Le Pen has made skilful use of some recent developments—including the financial-political scandal known as Clearstream—that increase that sense. The French no longer trust their politicians, he argues, because they have heard many false promises. Politicians said the euro would bring growth and jobs; voters see neither. When Dominique de Villepin, the prime minister, says unemployment has fallen to 9%, and will drop to 8% next year, many citizens don t believe him the figures, they say, must be wrong. Could the far-right leader repeat his 2002 performance next year? Quite possibly. Fully 23% of voters said in one recent poll that they agreed with Mr Le Pen s ideas, and 31% wanted him to stand again. No fewer than 36% guessed he would again make it into the second round. His chances depend largely on who his rivals are. Polls suggest that if the charism fuel dispenser
